The volume of a cylinder is V= b x h or V=pi x r^2 x h

The surface area of a cylinder is SA= L+ 2(base area)

Cylinder= is a solid that consists of a circular region and its translated image on a parallel plane.

Base= the faces formed by the circular reion and its translated image are called the bases of the cylinder.

Cones= a cone is a three-dimensional figure that consists of a circulat base and a curved lateral surface that connects the vase to a single point not in the plane of the base called the vertex.

an altitude of a cylinder is a segment that has end points in the planes containing the bases and is perpindicular to both planes.
